What are the articulating bones of the humerus?

What are the articulating bones of the humerus?

The humerus is the single bone of the upper arm region. It articulates with the radius and ulna bones of the forearm to form the elbow joint. The humerus is the single bone of the upper arm region (Figure 1). At its proximal end is the head of the humerus.

What is between the radius and humerus?

The humeroradial joint is the joint between the head of the radius and the capitulum of the humerus, is a limited ball-and-socket joint, hinge type of synovial joint.

Which bone articulates the most with the humerus?

The humerus is a bone in the upper arm. It runs from the shoulder to the elbow. Proximally it articulates with the scapula to form the shoulder joint, or glenohumeral joint. Distally, the humerus articulates with the radius and ulna to form the elbow joint.

Which bone marking articulates with the radius?

ulna
Radial notch (incisura radialis) is a depression along the lateral edge of the coronoid process that articulates with the head of the radius. The joint allows the radial head to rotate against the proximal end of the ulna during pronation and supination.

What does the radius articulate with?

The radius articulates proximally at the elbow with the capitulum of the humerus and the radial notch of the ulna. It articulates at its distal end with the ulna at the ulnar notch and with the articular surfaces of the scaphoid and lunate carpal bones.

What is radius bone?

radius, in anatomy, the outer of the two bones of the forearm when viewed with the palm facing forward. All land vertebrates have this bone. The head of the radius is disk-shaped; its upper concave surface articulates with the humerus (upper arm bone) above, and the side surface articulates with the ulna.

Which bone is the radius?

radius, in anatomy, the outer of the two bones of the forearm when viewed with the palm facing forward. All land vertebrates have this bone. In humans it is shorter than the other bone of the forearm, the ulna.

What structure articulates on the humerus articulates with the coronoid process of the ulna?

The proximal end of the ulna resembles a crescent wrench with its large, C-shaped trochlear notch. This region articulates with the trochlea of the humerus as part of the elbow joint. The inferior margin of the trochlear notch is formed by a prominent lip of bone called the coronoid process of the ulna.

Does humerus articulate with radius or ulna?

Humerus and Elbow Joint The humerus is the single bone of the upper arm region. It articulates with the radius and ulna bones of the forearm to form the elbow joint.

What does the Trochlea articulate with?

The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna.

Does radius articulate with humerus?

Is the radius connected to the humerus?

The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.
